just new frames with vintage engines eh?

bob, my backup bike only needs to take me at most 3 miles a day five days a week. i have good to excellent mechanical skill and i seem to have some kind of magnetic field that keeps things running. had a backfire coming home from work one day that blew the carbs out of their boots, rode it home ready to push it off a cliff till i pulled the cover off and saw the problem

I wouldn't want one as my only ride, but for a 2nd or 3rd bike, just for the fix, I would like to have something old, smokey and scary.

Less reliable because they don't have cams, cam chains, cam chain tensioners, valves, and valve springs? My GT550 was the most reliable bike I ever had.

My experiences with 2 stroke bikes involves an RD250 that was beat on alot, and ridden harder than a prostitute in a prison.

I've owned, or been owned by at least 9 two strokes that I can remember.
I beat the ever living shit out of most of them, drag raced and road raced 2-strokes. They all have the same problems. The rings don't spin, the cranks are pressed and heat. The ring and heat thing cause quicker wear to the top end, and if run really hard the cranks can twist. The crank shaft fix is a spot weld to hold the crank pins to the flywheels. The heat from a power stroke every time the piston goes down warps things and the rings wear from passing over the port windows. Liquid cooling helps, but heat is heat and with no waste cycle to cool down between power strokes they do run hotter. A 2-stroke will need a topend refresh at least twice as often as a 4-stroke or more. Good part is they are easy and cheap to renew. There is no valve train, there is no valves, cams, chains, rockers,followers..nothing. Pistons, rings and bores, is the whole thing. Fact.
Bob mentioned the RD250. Most of my 2-stroke experience is with RD air cooled engines, and they are tuff little bastards. When they are built right and tuned right, they rock! On the other hand, like most all 2-strokes, they are touchy about tuning and a little off here or there and they will drive you up a wall with frustration. But a topend rebuild takes about one hour of wrench time and costs about $150. for a twin. Ever rebuild a 4-stroke twin topend? Not even close on time or money.
My RD350s would make around 70HP when cool and level off at about 55-58HP when hot, in a 300LB bike with a 52in wheel base. Vintage racing against 350 Honda 4-strokes was ridiculous, it would devastate them and I had to compete with the 750s. A 4-stroke 750 better be very good or it would be in the background. They did require more fiddling, but I could rebuild the topend during the lunch break and still have time to help the 4-stroke guys load their bikes to go home when they needed the same thing...

My GS1000 has a built-up crankshaft with roller bearings. I've over-revved it about a zillion times and it still pulls like it did when new. As Suzuki's first four-stroke design, they say it was over-built. I agree.

I rode two-stroke street bikes for eight years before I got the GS. RD400's and H1's would beat my GT550 in a straight line, but the GT had a torque curve that looked like a big scoop of ice cream. Perfect for accelerating out of sharp corners. I never did anything to the engine, but I highly modified the suspension. The front had modified damper rods, added fork bearings, fork brace, and modified springs. The rear shocks were about an inch taller than stock.

And that three cylinder was so smooth. Too bad it had a weak ignition. And replacing and adjusting three sets of points and condensers was a pain and expensive.
